Predatory business practices succeed on exposure rate. F2P, maximum exposure minimum expectations. Subscription service, big exposure, little expectations. Buy out right, smallest exposure, maximum expectations.

F2P made it easier to get the current loot box infested mess.
Subscriptions services also make it easier to add these kind of things.
The biggest complaints come from full price games adding MTX, is it not? F2P and to a lesser extent game on gamepass, often get a pass for adding more MTX (and possibly later NFTs) to the games.

The source of the problem is the race to the bottom when it comes to luring people in, then needing ways to pay for it all.

BOTW and Halo are two fundamentally different games for people with fundamentally different tastes. Comparing the two of them is almost like comparing FH5 and BOTW just because they are "open-world." People go into these games looking for different things and I truly do not believe that a BoTW's style open-world would work in a Halo game.

Besides, I feel like "Ubisoft Style" is the new buzzworld that people like to throw around these days without taking two seconds to think in what they're actually saying. You can find more similarities between Ghost of Tsushima and AC:Odissey than between AC:Odissey and FC6; and you can find more similarities between Inmortals Fenyx Rising and BoTW than between Fenyx Rising and Valhalla.

It makes sense for F2P games, as they are free and anyone thinking that a F2P game doesn't deserve to have some sort of monitorization in them will come across as entitled. A company needs some sort of income after giving their product out for free. 

We pay full price for games today and still have heavy lootboxes and MTXs so its not going away and only growing with the basic full price games.

The games on Game Pass are not mobile games or exclusive service games. They are made like all others and are sold at regular prices as well as being offered on GP. You could have a point if the games are Game Pass exclusive and built from the ground up for GP, meaning you cannot buy the game outright and its only access point is via the service fee. This is not the case with Stalker 2 and many other day one releases on GP. 

Tell me, how does a Service pioneer predatory business practices? Especially from companies who don't own the service? Remember all games on GP can be purchased just like every other game on any other platform.

It didn't pioneer it, I never said that. It facilitates predatory business practices, enables them, makes it easier to be swallowed by the players.

Remember the 'outrage' when Dragon Age had quest persons in game that prompted you to buy the DLC? Now I'm playing FH4 again I get bombarded with commercials for the DLC. Just got an unskippable commercial for the Lego expansion, had one earlier as well. And every loading screen is promoting the DLC packs, car packs. The DLC is already integrated in the menu as well, car pack cars already in the 'show rooms'.

It makes sense for F2P games, as they are free and anyone thinking that a F2P game doesn't deserve to have some sort of monitorization in them will come across as entitled.

And it makes sense for services as well, same thinking (to a lesser extent). It's ok because you didn't pay full price. It's ok because you don't have to buy them. It's ok because you can still grind your way through. And so on and so on, and here we are. Loot boxes, MTX, bombarded with please buy this, buy that. And indeed whether you play them on the service of buy the full game, you get the same treatment. That's the real shame.
